You must register the Storwize® V3500 ports
with an EMC CLARiiON controller if Access Logix is installed.
Before you begin
The following prerequisites must be met before you can register
the
Storwize V3500 ports
with an EMC CLARiiON controller that has Access Logix installed:
- The EMC CLARiiON controller is not connected to the system
- You have a RAID controller with LUs and you identified the LUs that you want to present to the
Storwize V3500 system
About this task
Each initiator port [worldwide port name (WWPN)] must
be registered against a host name and against a target port to which
access is granted. Refer to Table 1. If a host has
multiple initiator ports, multiple table entries with the same host
name are listed. If a host is allowed access by using multiple target
ports, multiple table entries are listed. For Storwize V3500 hosts,
all WWPN entries should carry the same host name.
Table 1 lists the associations:

Procedure
- Connect the Fibre
Channel and zone the fabric as required.
- Issue the detectmdisk command-line interface
(CLI) command.
- Right-click on the storage system from the Enterprise Storage
window.
- Select Connectivity Status. The
Connectivity Status window is displayed.
- Click New. The Create Initiator
Record window is displayed.
- Wait for the list of Storwize V3500 ports
to appear in the dialog box. Use the WWPN to identify them. This process
can take several minutes.
- Click Group Edit.
- Select all instances of all the Storwize V3500 ports
in the Available dialog box.
- Click the right arrow to move them to the selected box.
- Fill in the HBA WWN field. You must
know the following information:
- WWNN of each Storwize V3500 node in the
clustered system
- WWPN of each port ID for each node on the system
The HBA WWN field is made up of the WWNN and the WWPN for the Storwize V3500 port.
The following output is an example:50:05:07:68:01:00:8B:D8:50:05:07:68:01:20:8B:D8
- Select A in the field marked SP and 0 in the SP Port field.
- Select CLARiiON Open in the drop-down
list of the Initiator Type field.
- Deselect the ArrayCommPath checkbox if it has been selected.
- Select 2 in the drop-down list of the Failover
Mode field.
Attention: Failure
to select failover mode 2 prevents the system from being able to fail
over I/O. Your data might become unavailable in the event of a single
failure.
- If this is the first time that a port was registered,
ensure that you select the New Host option.
Otherwise, select Existing Host.
- Ensure that the same host name is entered for each port
that is registered.
- Select Array in the drop-down list
of the Unit Serial Number field.
- Assign a host name in the Host Name field.
- Click OK.
- Specify the IP address of your switch. The EMC CLARiiON
does not use this IP address. However it must be unique (within the
EMC CLARiiON) to prevent errant behavior by Navisphere.
- Repeat step 11 for all possible combinations.
The following example shows the different combinations of a system
with four ports:
- SP: A SP Port: 0
- SP: A SP Port: 1
- SP: B SP Port: 0
- SP: B SP Port: 1
- Repeat steps 1 to 19 to register the rest
of your Storwize V3500 WWPNs.
Results
All your WWPNs are registered against the host name that
you specified.
